At the moment I don't see the point in choosing and buying coins because I did it earlier and now I'm just waiting for my coins to grow and bring me the arrival.
Now it is not the right time, to purchase the altcoins because the market seems to be in an upward trend. So instead of buying at the current situation, better hold some funds for buying altcoins when their prices drop, in trading, we should always hold our profits to purchase altcoins when the price drops.
